Question

Transpiration is helpful to plants in:

• A. Upward conduction/ascent of sap
• B. Loss of excess nutrients
• C. Cooling
• D. Loss of excess water

Answer 1

The correct option is D Loss of excess water

Functions of Transpiration are :

1. Help in ascent of sap

2. Cooling of the plant since water vapours take up the heat of plant.

3. It regulates the amount of water by losing excess water in form of vapours.

It doesn't help in loss of excess nutrients as water vapours do not contain any nutrients and they're left behind in the plant.

So the correct answer is ' loss of excess water'.
